Taz

Taz is an Internt worm, which spreads by e-mail in messages with infected attachments and through IRC networks. It uses Microsoft Outlook mail application and mIRC or pIRCh chat clients to distribute itself to other users. It also may show a simple message window, disclosing its presence in a computer. The worm is written in Visual Basic applicationming language and requires some files to run. If no such files are found in a computer, Taz doesn't work at all.
